DataSource Controls :: How To Change A Table Column Data Type
Jan 21, 2010I attempted to change a table columns data type and in the process caused a lot of issues. I had a date column in one of my tables and stupidly changed it from varchar to date. When I tried to run queries on it I keep getting the 'cant find column 3 error'. Now that tables structure is :
[Code]...
So column 4 is actually the date column. All other queries work for this table. I then tried to change it back and then copied all data to a new table and now I am using the new table and converting the dates as needed but I am still getting the error.
SELECT * FROM postlinks WHERE postlinks.date >= CONVERT(datetime,CONVERT(varchar(10),GetDate(),112))

May 14, 2010I am trying to store data from an XML file to a table in my database, but I keep getting the same error.

And this is my error:

In my XML file I have both existing rows and new rows for the database table. I'm guessing I have to do something to sort out the the rows that are not already in the database, but so far I have been unsuccessful to figure this out.

DataSource Controls :: Database Table: Move Row To The Top Of The Table?
Sep 5, 2010I have a table in my aspnet database. I added a bottom row "Not Selected", if the user doesn't select from a databound drop down list.

There is not "cut" and "paste" when I select the whole row.

DataSource Controls :: Type Safe SQL Parameters And Update/ Insert Of Database
Feb 1, 2010I have been in the process of updating my code with security methods, and I've been learning this from [URL] (or "Security Guidelines: ASP.NET 2.0"). In the middle of the page under "When Constructing SQL Queries, Use Type Safe SQL Parameters" it says "Use type safe parameters when constructing SQL queries to avoid possible SQL injection attacks that can occur with unfiltered input". Now, what they suggested was to use code like:
"DataSet userDataset = new DataSet();
SqlDataAdapter myCommand = new SqlDataAdapter(LoginStoredProcedure", connection);
myCommand.SelectCommand.CommandType = CommandType.StoredProcedure;
myCommand.SelectCommand.Parameters.Add("@au_id", SqlDbType.VarChar, 11);........"
But, I was already using code like:
"var dataSource = (SqlDataSource)form1.FindControl("sqlDataSource5") ;
dataSource.UpdateParameters.Add("someVal", val);"
So now, to use type safe parameters, I decided to include it like:
"var dataSource = (SqlDataSource)form1.FindControl("sqlDataSource5") ;
dataSource.UpdateParameters.Add("@someVal", DbType.Int16, val);
dataSource.UpdateParameters["@someVal"].Size = 1;"
So, that would be how I would modify my current code base to use type safe parameters in sql updating/inserting.
Getting to my actual question, as it was said "Use type safe parameters when constructing SQL queries to avoid possible SQL injection attacks that can occur with unfiltered input". First off, this suggests that this should apply to unfiltered input. Also, in their example they only did this for an ID.
So, what I'd like to know, when it comes to "unfiltered input", does this mean as long as the input is unfiltered I must use type safe parameters, or even filtered input shall have this (just to be sure), like, input that has been ran through a regularexpression check? Shall I do this for all values I insert/update into the database, or just IDs and important things?
The way I see it right now is that it would be a good precaution to just do type safe checks on everything (literally) that updates/inserts into the database just to be extra safe. But, I really am unsure if this is really the best idea, because if I did, would this possibly cause overprocessing of information? Can this cause too much strain on server resources? If my fears serve true, what would be a good suggestion of how I could implement this properly without having to worry about what I said?

DataSource Controls :: How To Truncate A String In A Database Table
Jun 14, 2010I get an error when I try to update a row in an SQL database table with a string of fewer characters than were previously stored. I attempted to correct this problem by using the "PadRight" function in my C# webpage event handler to fill in the remaining characters with spaces, but I don't seem to be able to make that work. So, what do I do when I want to store fewer characters in a table row that has more characters previously stored in it?
